Abstract (en)
[origin: EP0347657A2] A wetness indicating hot-melt adhesive which changes color in response to the presence of moisture is disclosed, which contains 20 to 70 wt. % of polymer, about 28 to 10 wt. % of which is water sensitive polymer; 25 to 60% of organic acid which is selected from a high acid fatty acid, or rosin acid, or a combination thereof; 0 to 40% of water soluble wax; 0 to 60 wt. of glycerlo monostearate; 0 to 55 wt. % of hydrogenated castor oil; 0 to 15 wt. % of polyalkylene wax; 0 to 60 wt. % of compatible plasticizer; and a wetness indicating agent which changes the color of the composition in response to moisture therein. The time of response of the color change can be controlled from about one second to a somewhat larger value as desired.
